' To all whom it may concern:

'lil

Be it known that we, Gnoncn B. MUNN and CHRISTIAN H. MARKER, citizens of the United States, residing at Warren, in the county of Warren and State of Pennsyl- Vania, have invented certain new and useful improvements in Fountain-Pens; and we do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which itappertains to make and use the Our invention consists in the novel features hereinafter described, reference being had to the accompanying drawing, in which we have illustrated two forms or embodiments of our invention, selected by us for purposes of illustration, and the 1 said invention is fully disclosed in the folmeans for holding the inktubes and pens in either raised or lowered position.

Fig. 4 is a diagrammatic view t8!k611 011 line H of Fig. 3 and showing the locking fingers in locked position in full lines and in unlocked position, in dotted lines.

Fig. 5 is a detail perspective viewof one" ofthe stamped'and bent supportin mem here for carrying the ink tubes, feeds and pens. W

Fig. 6 is a detail perspective Vl'BW of one of the ink feeds and a portion of one of the rubber ink tubes. r

Fig. 7 is adetail perspectlve view of another form of supporting member for parrying an ink tube,. ink teed andppn, in a fountain pen construction for writing with a single colored ink.

Une object of our invention is to rov de an improved duplex fountain pen avmg two separatercservoirs adapted to contam different colored inks, and a separate pen for each reservoir which may be moved into or out of the pen barrel with its re hilt spective ink reservoir or tube.

A further ob ect is to provide a duplex fountain pen in which the locking of one that changes member plate being a .tated. with and slide on the same.

pen in operative position, will cause the other pen to lock in inoperative position.

further object of the same is to provide a partition between the pens which will keep the same separated and prevent the ink from one pen, running onto the other.

A still further is to provide an improved supportin for the pens and their connectef which may be stamped or out from a sheet of metal.

With the foregoing with other objects in view, it will be apparent as the nature of the invention is better understood, that the present invention resides in the combination and arrangement of parts, and in the details of construction hereinafter set forth, it being understood in the precise embodiments of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention or sacrificing any of its advantages. in the embodiment of our invention illus trated in'Figs. 1 to 5 inclusive, 1 represents a pen barrel, which is preferably formed of hard rubber or the like, and is provided at its lower end with an inturned flange 2 for a purpose hereinafter mentioned, and said barrel is provided at its upper end with an internally threaded portion 2 for engagement with the external threads 4: of

a rlzxaip 5.

ounted in said barrel 1 and prevented from moving but a slight distance longitudinally of the barrel, by the flange 2 and cap 5, is a partition plate 6, which is the same width as the internal diameter of the pen barrel and is freely rotatable in said barrel.

Mounted in said of said means parts, single pen barrel on each side artitionplate 6, is a supporting which carries a flexible ink tube 8, an ink feed 9 and a writing pen 10, the tubes on the opposite sides of the partition ored inks, for instance, red and black.

'Each of the supporting members 7 is formed of a single sheet of metal cut to the form shown in Fig. 5, and having a fiat portion 11, which lies adjacent the partition plate 6 and is adapted to be Trioe members 7 are reduced in width, as shown at 12, and bent upon themselves at 13, to

object of our invention,

objects outlined, and.

apted to hold diflerent 001-,

secure the upper ends of the flexible ink tubes 8 to them, and -to form spring tongues 14, which are adapted to be forced toward which are integral with the flat portions 11 and are bent over upon the reduced portions 12.

Ihe ink feeds 9 are preferably formed ofhard rubber and have the usual ink ducts 16 and enlarged heads 17, which are inserted in the necks 18 of the ink tubes.

The pen points 10 lie upon the ink feeds in the usual manner and their upper ends abut against shoulders 20 formed by enlarging the heads of the ink barrels. The ink feeds 9 are held in the necks of the tubes 8 and the pens 10 are secured to the ink feeds by means of clips 21, which are inte ral with the flat portions 11 of the supcolor of the ink porting members 7, and are bent over the parts mentioned, as shown in Fig. 1.

From an lnspection of Fig. 1, it will be i seen that the pens, when not in use, rest entirely within the barrel 1 and that the partition plate 6 separates said pens and prevents the ink from one pen passing to the other, so that each pen writes only the which is contained in its respective ink tube.

When it is desired to use either one of the pens, it is necessary that the same should be brought to position below the barrel and this we provide for in the following manner.

The pen barrel 1, as best shown in Figs. 3 and 4, is provided on opposite sides with longitudinal slots 22 and 23, which open up- W-ardly at the top of the pen barrel 1, for a purpose hereinafter described. Circumferentially extending notches 24 and 25 are provided in the barrel 1 near its upper end and merge into the slots 22 and 23, both ofsaid notches being cut in the same circumferential direction fromtheir respective slots. The barrel 1 also has similar notches 26 which merge into the lower ends of the slots 22 and 23. Integral with each of the supporting members 7 is an arm 27 carrying at its outer end a finger engaging portion 28, and the arms pass through the slots 22 and 23 and are adapted to enter the notches 24 and 25 for securing the pens and their connected parts in upper or inoperative posi tion, or to enter the notches 26 for securing the pens in lower or operative position.

' In assembling the pen, the partition plate 6 is first inserted in the pen barrel 1 until its lower end rests on the flange 2, then the supporting members 7 carrying their. respective ink tubes 8, ink feeds 9 and pens 10, are

inserted in the barrel 1 on opposite sides of the partition plate 6. As the supporting mem ers pass into the barrel 1, their respective arms 27 enter the upper ends of the slots 22 and 23. When the supporting members 7 have been inserted a sufiicient distance into the barrel, the cap 5 is screwed on and this holds the parts within the pen barrel 1, and closes the upper ends of'the slots 22 and 23. I

From the drawings, it will be seen that the clips 21 when taken with the partition plate 6 form in effect a ring which is of slightly less circumference than the interior of the barrel 1, to provide frictional guides for the lower ends of the supporting members 7. The spring tongues 14, which may be forced inwardly to fill the tubes by inserting an instrument through the openings 30 in the pen barrel, also bear against the interior of the barrel 1 and assist in guiding and steadying the supporting members 7 and their connected parts.

In practice we propose to color the finger, engaging member 28 of the red ink su port-' ing member 7, red and the finger en aging member of the black ink supporting member, black. In operation, assuming that the pens are in inoperative position, if it is desired to use the black ink pen, you may do so, by pushing the black finger engaging member 28, out of its notch 24-and into the slot 22. This causes both supporting memhere 7 and the partition plate 6 to rotate slightly in the pen barrel 1 and also causes the red finger engaging member to move out of its locking notch 25. Then by forcing the black finger engaging member 28 downwardly in its slot 22, the black ink pen will be forced downwardly below the lower end of the barrel 1, but the red ink pen will remain stationary, owing to the friction set up by its clips 21 and spring tongue 14. When the arm 27 of the black finger engaging member 28 reaches the lower end of the slot 22, the black finger engaging ortion is rotated slightly to cause its arm 2 to enter. the notch 26 for locking the black ink pen in operative position, and this movement'also causes the arm27 of the red ink finger engaging portion, to move back into its locking notch 25 to lock the red ink pen in inoperative position. It isobvious that the red ink pen may be operated in a similar man ner by operating the red ink finger engaging member.

In the modification shown in Fig. 7, we propose to employ a pen barrel similar to the one shown in Fig. 1, except that we provide a slot and locking notches in one side of the barrel only. We also leave out from this construction, the partition plate 6 and employ only one supporting member 40, which is made exactly the same as that shown in shown at 4:2. The ink tube, ink feed and pen point are secured to this modified supporting member in a manner similar to that shown in the other figures. hen this supporting member is inserted in the pen barrel, the half sleeve 41 and the spring tongue 43 frictionally engage the interior ofthe pen barrel and prevent the same from moving except when operated by its finger engaging member (not shown). This modificaltion is designed to use but a single colored in From the foregoing, it will be apparent that we have devised an improved form of fountain pen which may be used with one or more differently colored inks and which is of such simple and practical construction,

that the same may be manufactured at a" small cost.

What we claim and desire to secure by Letters Patent is 1. A fountain pen comprising a pen barrel provided with a longitudinally extending slot and circumferentially arranged notches which merge into said slot, a plate rotatably mounted in said barrel, a supporting member slidably mounted on said plate and composed of a single sheet of metal bent upon itself to form a spring tongue, an ink tube secured to the supporting member by the bent portion of the same and arranged to be compressed by said tongue, integral clips provided on said supporting member, an ink feed and pen secured to the ink tube by said clips, and an operating arm. provided upon said supporting member and extending through said slot for rotating said member and plate and for sliding said member into operative and inoperative positions.

2. The combination with a fountain pen having an ink tube, an ink feed, and a pen, of a supporting member composed of a single sheet of metal bent upon itself to engage the rear end of the ink tube and to form a spring tongue to compress said tube when pressure is exerted on the tongue, and clips provided at the forward end of said member for securing the ink tube, ink feed and pen together.

3. A fountain pen comprising a pen barrel provided with oppositely disposed longitudinally extending slots and circumferentially arranged notches which merge into said slots, a partition plate rotatably mounted in said barrel, a supporting member mounted on each side of said partition plate and being adapted to slide on the same, operating arms provided upon said supporting members and extending through said slots said partition and sliding said members into operative and inoperative positions, and an ink reservoir, ink feed and pen carried by each of said supporting members.

4. A fountain pen comprising a barrel provided with oppositely disposed longitudinally extending slots and with upper and lower circumferentially arranged notches which merge into said slots, a partition plate rotatably mounted in said barrel, supporting members slidingly mounted in said barrel between said partition plate and the interior wall of said barrel, operating arms provided upon said supporting members and extending through said slots and having finger engaging members for rotating and sliding said su porting members, and an ink tube, an ink eed and a pen carried by each of said supporting members and being adapted to be lowered into operatiVe position or raised into inoperative po sition by said finger engaging portions.

In testimony whereof we affix our signatures.
